Vitamin D -energy increase and sleeping


Quote  |  Reply

I am on 2,200 mg of D3 and I feel great, lots more energy and love it

...but I am having trouble sleeping...it could be stress related not D3 related

...any one else notice disrupted sleep while on D3?

 

...did you notice the increased energy and alertness? (I feel very up/great really..I think it is the dopamine increase, but maybe my serotonin is low as well)

...I wake up with the sun now...like daybreak...then jog a bit...

Phew -- for a moment there 2200 mg was freaking me out.

I think you mean 2200 IU which is about 50 micrograms (mcg). 

The RDA (recommended daily allowance) is 100 mcg for an adult so your dosing is not dangerous. Good!

D3 is not a supplement to take like you would maybe Vitamin C.

While the body simply rids itself of any Vitamin C you ingest that it doesn't need, whereas D3 is a steroid hormone. It is fat soluble. Vitamin C is water soluble.

Treat all fat soluble vitamins with extreme care (Vitamin A is another one) and involve your doctor first. They are less readily removed from the system if not needed.

You may have seen recent media reports that supplementing our diets with D3 slashes cancer risks and boost immunity (recent media segments are all over its protective capability against Swine Flu). The underlying studies for cancer reduction and immuno-modulation are sound (Swine Flu -- no), but D3 is not a no-down-side supplement to take.

D3 can create hypercalcemia (excess calcium -- which actually would cause serious sleepiness, nausea, vomiting, metallic taste, bone pain, muscle pain...). It interacts negatively with a lot of commonly prescribed drugs as well.

While taking D3 your serum levels of calcium should be checked. And you want to confirm there is no underlying hidden liver or kidney illness before taking D3 as D3 could further damage those organs if you are susceptible.

To finally answer you question. Insomnia is not directly to taking D3 in a 50 mcg/day dose.

Your experience of increased energy and alertness is the fact that neural tissue has D3 receptors that subsequently encourages the production of various neurotransmitters.

It has not disrupted my sleep, as far as I can tell. But I have never had any problems with sleep disturbances as far as deprivation goes.

I think I do have more energy though. I am on the same dosage as you - about 5 drops of a liquid version.

I had several vitamin/mineral/other deficiencies so I am not sure which one has improved my energy - Vitamin D, Iron, and also a lowish thyroid count. 

Somehow with a multivitamin, d, and iron, my energy has improved - and also my thyroid count went back up a little on its own.

I hope that your sleep improves - the other effects - like jogging in the morning sound good.

I take mine at night and they have me on 3,000 ID for my bones and my allergy doctor said it would cut back on colds. Said he hadn't had any since starting it last year.

Allergy Remedies
Is It Possible to Go Natural?
The side effects of allergy medications keep some people from using them. Natural remedies can be a great alternative, but some are more effective than others.
